Genes affected
FBXO42 (HGNC:29249): (F-box protein 42) Members of the F-box protein family, such as FBXO42, are characterized by an approximately 40-amino acid F-box motif. SCF complexes, formed by SKP1 (SKP1A; MIM 601434), cullin (see CUL1; MIM 603134), and F-box proteins, act as protein-ubiquitin ligases. F-box proteins interact with SKP1 through the F box, and they interact with ubiquitination targets through other protein interaction domains (Jin et al., 2004 [PubMed 15520277]).[supplied by OMIM, Dec 2010]

The c.1990G>A (p.V664I) alteration is located in exon 10 (coding exon 9) of the FBXO42 gene. This alteration results from a G to A substitution at nucleotide position 1990, causing the valine (V) at amino acid position 664 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
